The liberal Mayor of Oakland, California warned illegal immigrants and their families of impending raids by federal authorities over the weekend, informing them that “credible sources” have confirmed possible sweeps by the Immigrations and Customs Enforcement in the coming days.

Mayor Libby Schaaf -who signaled she’d be willing to face jail-time over her refusal to cooperate with the federal government over immigration policy- told Bay Area residents to be on the look-out for possible ICE agents, but “go about their daily lives without fear.”

“We want residents to prepare, not panic. We understand ICE has used activity rumors in the past as a tactic to create fear; our intent is for our community to go about their daily lives without fear, but resiliency and awareness,” said Schaaf.

“My priority is for the well-being and safety of all residents -particularly our most vulnerable,” she added.
